Aigami (real name: Diva) is the main antagonist from the 2016 film Yu-Gi-Oh! The Dark Side of Dimensions. He is described as a mysterious youth who holds the keys to the movie's story.
He was voiced by Kento Hayashi in the Japanese version, and Daniel J. Edwards in the English dubbed version who also played Varis in Yu-Gi-Oh! VRAINS.
He was seen where he is manipulating Seto Kaiba into stealing the Millennium Puzzle from Yugi Muto, but Yugi was able to recomplete his Millennium Puzzle with the help from Seto Kaiba. He is one of the persons for solving the Millennium Puzzle before Yugi did it. He then enters in the Shrine of the Underworld to cause chaos with his pure evil monsters. He was first defeated by Seto Kaiba who has used Obelisk the Tormentor. He later returns to seek revenge against Seto Kaiba and Yugi Muto.
Aigami uses the Cube to absorb three of Yugi's friends in a attempt to murder Ryou Bakura, but he killed Mani instead. He was once again defeated by Yugi Muto. He attempts to absorb some of Yugi and Kaiba's friends, but he eventually succeeded absorbing Seto Kaiba instead. He attempts to absorb Yugi, but Dark Yugi (Atem) is able to give Yugi full strength to finish the job on Aigami with an upgraded Mahad, thus defeating Aigami and his Cubic monsters in the process.
Aigami then disappears, but he has good friendly terms with Sera and Mani, who was revived in the process.
